Might be a simple answer but trying to be sure before I make it. My wife was cleaning one of her clients house and found this and wants me to make it for her. Basically a big serving tray/cutting board, it’s 3 feet long so don’t know why there’s a juice groove since I doubt anyone would actually use it as a cutting board. Anyways, the edge of the board and and hole are a lot more rounded and blended into the board a lot more than I’ve ever done so wasn’t sure how to go about it. Was thinking a bigger round over but, the biggest one I’ve used is half inch, so wasn’t sure if that was the actual solution or not.

A roundover will get you started but really I’d be achieving part of that shape afterwards with a belt sander for the edges and a sanding drum in a drill for the hole with lots of moving around. If you don’t mind spending a little cash to save some time and maybe be more consistent maybe consider this router bit.

I made a serving board that had that kind of edge and hole profile for my mom out of lacewood 25 years ago using the belt sander method and it turned out nice. I should snap a photo of it next time I visit.
